Description

Technical Field

[0001] This invention relates to the field of power engineering technology, and in particular to a grounding pile and a grounding pile installation method. Background Technology

[0002] During the construction and maintenance of power transmission lines, it is often necessary to install grounding piles for lightning protection on power equipment. The main purpose of the grounding piles is to establish a reliable connection between the electrical system and the ground, so as to ensure that the current can flow effectively to the ground, thereby protecting the safety of personnel and equipment at the construction site.

[0003] Traditionally, grounding stakes are mostly installed manually by hammering them into the ground, which is time-consuming, labor-intensive, and inefficient. Currently, there are grounding stakes installed using motor-driven methods, but these grounding stakes are prone to shaking during installation and have poor stability. This results in the stake not being firmly inserted into the ground, and the entire stake is prone to displacement or even being pulled out, thus affecting the normal use of the grounding stake. Summary of the Invention

[0004] The purpose of this invention is to provide a grounding pile and a grounding pile installation method, which can improve the stability and firmness of the pile installation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Grounding stakes, including:

[0007] Outer frame;

[0008] pile body;

[0009] The height adjustment unit includes a first drive assembly, a fixed plate, and a slide. The fixed plate is disposed on the outer frame, and the slide is height-adjustably disposed on the fixed plate. The first drive assembly is used to drive the slide to move on the fixed plate.

[0010] The hammering unit includes a second drive assembly, a hammering rod, and a spring. The second drive assembly is disposed on the slide table, the hammering rod is movably disposed on the second drive assembly, and the spring is disposed between the hammering rod and the slide table along the height direction. The hammering rod has a hammering position and a lifting position. In the hammering position, the spring is in an extended state, and the hammering rod abuts against the pile body. In the lifting position, the hammering rod is disengaged from the pile body, and the spring is in a fully compressed state. The second drive assembly can be connected to the hammering rod and drive the hammering rod to move along a first direction, so that the hammering rod moves from the hammering position to the lifting position. The second drive assembly can also be disengaged from the hammering rod, so that the hammering rod moves from the lifting position to the hammering position in the opposite direction of the first direction under the action of gravity and the elastic force of the spring.

[0011] A limiting component is provided on the outer frame, and a limiting hole matching the pile body is provided on the limiting component, and the pile body is vertically inserted through the limiting hole.

[0012] Preferably, the second drive assembly includes a first motor, a rotating lever, a stop block, and a rotating disk. The first motor is mounted on the slide table, the rotating disk is rotatably mounted on the slide table, the rotating lever is mounted at the output end of the first motor, the stop block is mounted on the rotating disk and away from the rotation center of the rotating disk, and one end of the hammer rod is mounted on the rotating disk and away from the rotation center of the rotating disk. The rotating lever can rotate forward and abut against the stop block, so that the stop block drives the hammer rod to rotate forward to the lifting position via the rotating disk.

[0013] Preferably, the hammer rod includes a crankshaft and a push rod hinged together. The end of the crankshaft away from the push rod is connected to the rotating disk via a pin. The end of the push rod away from the crankshaft can abut against the pile body. The spring is disposed between the push rod and the slide table along the height direction.

[0014] The grounding stake also includes a positioning seat, which is disposed on the slide. The positioning seat has a positioning hole that matches the push rod. The hammer rod is vertically inserted into the positioning hole, and the axis of the positioning hole coincides with the axis of the limiting hole.

[0015] Preferably, at least two limiting components are provided, and at least two limiting components are vertically arranged on the outer frame.

[0016] Preferably, the limiting component includes a first clamp and a second clamp that are detachably connected. The first clamp is disposed on the outer frame, and a limiting hole is formed between the first clamp and the second clamp. The pile is vertically inserted into the limiting hole and abuts against the first clamp and the second clamp.

[0017] Preferably, the grounding pile further includes a locking component, which includes a pin and a mounting base. The mounting base is disposed on the second clamp, the pin passes through the mounting base, and the pile body has a pin hole that matches the pin.

[0018] Preferably, the first drive assembly includes a second motor, a lead screw, a guide rod, and a fixed base. The fixed base is disposed on the fixed plate, and the lead screw and guide rod are disposed on the fixed base along the height direction. The slide is passed through the guide rod and threadedly engaged with the lead screw. The output end of the second motor is connected to the lead screw.

[0019] Preferably, the bottom of the outer frame is provided with a ground cone support.

[0020] Preferably, the end of the hammer rod near the pile body is provided with a cylindrical hammer seat, the cross-section of which is larger than the cross-section of the hammer rod and the pile body.

[0021] The grounding stake installation method, using the above-mentioned grounding stake, includes the following steps:

[0022] S1. Place the outer frame on the ground, start the first drive assembly, and adjust the hammer rod to a suitable hammering height through the slide table;

[0023] S2. Activate the second drive assembly to move the hammer rod to the lifting position along the first direction; the second drive assembly disengages from the hammer rod, and the hammer rod moves to the hammering position in the opposite direction to the first direction under the action of gravity and the elastic force of the spring, so as to hammer the pile body;

[0024] S3. Repeat step S2 until the pile is inserted into the ground to a suitable depth.

[0025] The beneficial effects of this invention are as follows:

[0026] The grounding pile provided by this invention, when the hammer rod is in the raised position, is detached from the pile body, and the spring is in its maximum compressed state. At this time, the elastic force of the spring on the hammer rod increases, thus preparing for the next hammering. Since the first driving assembly can be disengaged from the hammer rod, the hammer rod can abut against the pile body in the opposite direction of the first direction under the action of gravity and the elastic force of the spring, thereby hammering the pile body to insert it into the ground. Since the first driving assembly can also drive the hammer rod to move along the first direction to move the hammer rod to the raised position, it can realize multiple reciprocating hammering of the pile body, thereby further increasing the depth of the pile body inserted into the ground, making the pile body less likely to be pulled out and extending its service life. Because the first drive assembly is mounted on the slide, the slide can be driven by the first drive component to change its installation height on the fixed plate. Therefore, the height of the hammer rod is adjustable, and construction personnel can adjust the hammering position of the hammer rod according to the actual requirements of the site to ensure that the hammer rod can always hit the pile. Because the grounding pile is equipped with a limiting assembly, the pile is vertically inserted into the limiting hole of the limiting assembly. The limiting hole matches the pile, so it can prevent the pile from shaking when hammering, thus ensuring the stability of the pile installation. In addition, the limiting assembly and the fixed plate are both mounted on the outer frame to form an integral structure. When the pile is installed, the outer frame is placed on the ground, which further improves the stability of the pile installation.

[0027] Using this grounding pile installation method, the first drive unit adjusts the hammer rod to a suitable hammering height via a slide table, thereby ensuring that the hammer rod can always hammer the pile body, and at the same time, it can adjust the drilling depth of the pile body; the second drive unit is activated to move the hammer rod to the lifting position, and then the hammer rod hammers the pile body under its own weight and spring force, and so on, thereby realizing repeated automatic hammering of the pile body until the pile body reaches the specified depth.

[0045] Example 1

[0046] like Figure 1 and Figure 2As shown, this embodiment provides a grounding stake, which includes an outer frame 1, a stake body 2, a height adjustment unit 3, a hammering unit 4, and a limiting component 5. The height adjustment unit 3 includes a first drive component 31, a fixed plate 32, and a slide 33. The fixed plate 32 is disposed on the outer frame 1, and the slide 33 is height-adjustably disposed on the fixed plate 32. The first drive component 31 is used to drive the slide 33 to move on the fixed plate 32. The hammering unit 4 includes a second drive component 41, a hammering rod 42, and a spring 43. The second drive component 41 is disposed on the slide 33, the hammering rod 42 is movably disposed on the second drive component 41, and the spring 43 moves along the height direction. A hammer rod 42 is positioned between a hammering rod 42 and a sliding table 33. The hammering rod 42 has a hammering position and a lifting position. In the hammering position, the spring 43 is in an extended state, and the hammering rod 42 abuts against the pile body 2. In the lifting position, the hammering rod 42 is disengaged from the pile body 2, and the spring 43 is in a fully compressed state. A second drive assembly 41 can be connected to the hammering rod 42 and drive the hammering rod 42 to move along a first direction, so that the hammering rod 42 moves from the hammering position to the lifting position. The second drive assembly 41 can also be disengaged from the hammering rod 42, so that the hammering rod 42 moves from the lifting position to the hammering position in the opposite direction of the first direction under the action of gravity and the elastic force of the spring 43.In this embodiment, when the hammer rod 42 is in the raised position, the hammer rod 42 is detached from the pile body 2, and the spring 43 is further compressed. At this time, the elastic force of the spring 43 on the hammer rod 42 increases, thus preparing for the next hammering. Since the first drive assembly 31 can be disengaged from the hammer rod 42, the hammer rod 42 can abut against the pile body 2 in the opposite direction of the first direction under the action of gravity and the elastic force of the spring 43, thereby hammering the pile body 2 to insert it into the ground. Since the first drive assembly 31 can also drive the hammer rod 42 to move along the first direction to move the hammer rod 42 to the raised position, so as to realize repeated hammering of the pile body 2, thereby further increasing the depth of the pile body 2 inserted into the ground, making the pile body 2 less likely to be pulled out and extending its service life. Since the first drive assembly 31 is set on the slide table 33, the slide table 33 can be driven by the first drive component 31 to change the installation height on the fixed plate 32, so the height of the hammer rod 42 is adjustable. Personnel can adjust the height of the hammering position of the hammering rod 42 according to the actual requirements of the site to ensure that the hammering rod 42 can always hammer the pile body 2. For example, when it is necessary to deepen the embedment depth of the pile body 2 at this location, the construction personnel can move the slide table 33 in the opposite direction of the first direction through the first drive component 31. At this time, the slide table 33 drives the second drive component 41 and the hammering rod 42 to a lower height, so the hammering rod 42 can hammer the pile body 2 into a deeper position in the ground. Specifically, when the hammering rod 42 is in the hammering position, the second drive component 41 can drive the hammering rod 42 to move to the lifting position in the first direction. When the hammering rod 42 reaches the lifting position, the second drive component 41 disengages from the hammering rod 42. At this time, the hammering rod 42 moves to the hammering position under the action of the elastic force of the spring 43 and its own weight. Then, the second drive component 41 drives the hammering rod 42 from the hammering position to the lifting position. This cycle is repeated to achieve repeated hammering of the pile body 2, so that it is driven into the ground.

[0047] A limiting component 5 is installed on the outer frame 1, and a limiting hole matching the pile body 2 is opened on the limiting component 5. The pile body 2 is vertically inserted into the limiting hole. In this embodiment, since the grounding pile is equipped with a limiting component 5 and the pile body 2 is inserted into the limiting hole of the limiting component 5, the limiting hole matches the pile body 2, thus preventing the pile body 2 from swaying horizontally, thereby ensuring the stability of the pile body 2 installation. Specifically, the outer frame 1 is a cuboid frame structure welded from metal rods. The limiting component 5 and the fixing plate 32 are both installed on the outer frame 1, thus forming an integral structure. When using the grounding pile, the construction personnel place the outer frame 1 on the ground, increasing the contact area between the grounding pile and the ground, further improving the stability of the pile body 2 installation.

[0048] Furthermore, such as Figure 4 and Figure 5As shown, the second drive assembly 41 includes a first motor 412, a rotating lever 413, a stop block 414, and a rotating disk 415. The first motor 412 is mounted on the slide table 33, the rotating disk 415 is rotatably mounted on the slide table 33, the rotating lever 413 is located at the output end of the first motor 412, the stop block 414 is located on the rotating disk 415 and away from the rotation center of the rotating disk 415, and one end of the hammer rod 42 is located on the rotating disk 415 and away from the rotation center of the rotating disk 415. The rotating lever 413 can rotate forward and abut against the stop block 414, so that the stop block 414 drives the hammer rod 42 to rotate forward to the lifting position through the rotating disk 415. In this embodiment, a support plate is provided on the slide table 33. The first motor 412 is connected to the slide table 33 through the support plate. The rotating lever 413 is a long strip structure, with its center part sleeved on the output shaft of the first motor 412. The first motor 412 can drive the rotating lever 413 to rotate. The rotating disk 415 is rotatably mounted on the support plate of the slide table 33. The rotation center of the rotating disk 415 is concentric with the rotation center of the rotating lever 413 (i.e., the output shaft of the first motor 412). A stop block 414 protruding from the rotation plane is provided on the rotating disk 415 away from the rotation center. The end of the hammer rod 42 is rotatably mounted on the rotating disk 415 away from the rotation center through a pin. Therefore, when the rotating disk 415 rotates, it can drive the hammer rod 42 to move up and down in the vertical direction. When the long strip rotating lever 413 rotates, its end can be aligned with the stop block. 414 contacts, thereby driving the rotating disk 415 to rotate through the stop 414. Since the rotating lever 413 and the stop 414 are in one-sided movable contact, the rotating lever 413 can only abut against the stop 414 when rotating in the forward direction and drive the hammer rod 42 from the hammering position to the lifting position through the rotating disk 415. When the hammer rod 42 rotates to the lifting position, the hammer rod 42 and the spring 43 vertically installed on the bearing plate of the slide table 33 reach the maximum compression state. When the hammer rod 42 has just rotated past the lifting position under the drive of the rotating disk 415, the hammer rod 42 will quickly move down to the hammering position under the action of its own weight and the elastic force of the spring 43, thereby hammering the pile 2 below to make it chisel into the ground. During the process of the hammer rod 42 moving from the lifting position to the hammering position, the rotating lever 413 disengages from the stop 414.

[0049] Specifically, such as Figure 1 , Figure 4 as well as Figure 5As shown, the hammer rod 42 includes a crankshaft 421 and a push rod 422 that are hinged to each other. The end of the crankshaft 421 away from the push rod 422 is connected to the rotating disk 415 by a pin. The end of the push rod 422 away from the crankshaft 421 can abut against the pile body 2. The spring 43 is arranged between the push rod 422 and the slide table 33 along the height direction. The grounding pile also includes a positioning seat 6, which is arranged on the slide table 33. The positioning seat 6 has a positioning hole that matches the push rod 422. The hammer rod 42 is vertically inserted into the positioning hole, and the axis of the positioning hole coincides with the axis of the limiting hole. In this embodiment, one end of the crankshaft 421 is rotatably mounted on the rotating disk 415 via a pin, and the other end of the crankshaft 421 is rotatably connected to the push rod 422 via a pin. A positioning seat 6 is provided on the bearing plate of the slide table 33, and a positioning hole is provided on the positioning seat 6. The push rod 422 passes through the positioning hole in the opposite direction of the first direction. Since the positioning hole matches the push rod 422, it can prevent the push rod 422 from swaying horizontally when it moves up and down, thereby ensuring that the push rod 422 can stably and accurately hammer onto the pile body 2. When the rotating disk 415 drives the crankshaft 421 to rotate, the motion trajectory of the crankshaft 421 connected to the rotating disk 415 is a circle with the rotation center of the rotating disk 415 as the center. Since the crankshaft 421 and the push rod 422 are rotatably connected by a pin and the push rod 422 is limited by the positioning seat 6, the circular motion of the end of the crankshaft 421 driven by the rotating disk 415 can be transformed into the vertical up-and-down motion of the push rod 422. This allows the hammer rod 42 to switch between the hammering position and the lifting position, and to repeatedly hammer the pile body 2.

[0050] Furthermore, such as Figure 1 As shown, at least two limiting components 5 are provided, and both limiting components 5 are vertically arranged on the outer frame 1. Specifically, at least two limiting components 5 are provided along the height, thereby making the pile 2 more stable and less prone to tilting when it is driven into the ground.

[0051] Furthermore, such as Figure 1 and Figure 3As shown, the limiting component 5 includes a detachably connected first clamp 51 and second clamp 52. The first clamp 51 is disposed on the outer frame 1, and a limiting hole is formed between the first clamp 51 and the second clamp 52. The pile body 2 is vertically inserted into the limiting hole and abuts against the first clamp 51 and the second clamp 52. In this embodiment, both the first clamp 51 and the second clamp 52 are semi-circular structures, arranged opposite each other, thereby forming a circular limiting hole in the middle, which matches the cross-sectional shape of the pile body 2, thus providing better stability for the pile body 2. The first clamp 51 and the second clamp 52 are detachably connected by a screw. When the pile body 2 is driven into the ground to a suitable depth (generally, the upper half of the pile body 2 is still exposed above the ground and inserted into the limiting hole), the construction personnel can remove the second clamp 52 from the first clamp 51, thereby completing the rapid separation of the outer frame 1 and the pile body 2, making it convenient for the construction personnel to remove the outer frame 1.

[0052] Specifically, such as Figure 2 and Figure 3 As shown, the grounding pile also includes a locking component 7, which includes a pin 71 and a mounting base 72. The mounting base 72 is disposed on the second clamp 52, and the pin 71 passes through the mounting base 72. A pin hole matching the pin 71 is opened on the pile body 2. In this embodiment, the second clamp 52 is provided with a mounting base 72, and a pin hole matching the pin 71 is opened on the side of the pile body 2. The pin 71 passes through the mounting base 72, and the end of the pin 71 can be inserted into the pin hole of the pile body 2, thereby locking the vertical position of the pile body 2 and preventing the pile body 2 from moving up and down in the limiting component 5, making it convenient for construction personnel to carry and move the grounding pile before operation.

[0053] Furthermore, such as Figure 2 and Figure 4 The first drive assembly 31 includes a second motor 311, a lead screw 312, a guide rod 313, and a fixed base 314. The fixed base 314 is mounted on a fixed plate 32. The lead screw 312 and the guide rod 313 are mounted on the fixed base 314 along the height direction. A slide 33 passes through the guide rod 313 and is threadedly engaged with the lead screw 312. The output end of the second motor 311 is connected to the lead screw 312. Specifically, the first drive assembly 31 is a lead screw guide rail device. The lead screw 312 and the guide rod 313 are vertically arranged between two fixed bases 314. The slide 33 is mounted on the lead screw 312 and is threadedly engaged with it. The second motor 311 is used to drive the lead screw 312 to rotate. When the lead screw 312 rotates, the slide 33 can move vertically up and down.

[0054] Furthermore, such as Figure 1As shown, a ground cone support 11 is provided at the bottom of the outer frame 1. Specifically, the ground cone support 11 is conical and threadedly connected to the outer frame 1. When the ground where the pile body 2 is to be buried is soft and uneven muddy ground, the ground cone support 11 can be inserted into the mud and the flatness of the outer frame 1 can be adjusted by screwing the ground cone support 11, thereby playing a role in stabilizing the outer frame 1.

[0055] Furthermore, such as Figure 1 As shown, a cylindrical hammer seat 423 is provided at the end of the hammer rod 42 near the pile body 2. The cross-section of the hammer seat 423 is larger than the cross-sections of the hammer rod 42 and the pile body 2. Specifically, a cylindrical hammer seat 423 is provided at the bottom end of the push rod 422 of the hammer rod 42. The cross-sectional diameter of the hammer seat 423 is larger than the cross-sectional diameter of the push rod 422 and the cross-sectional diameter of the pile body 2, thereby increasing the contact area between the hammer rod 42 and the pile body 2 and ensuring the stability of the pile body 2 during installation.

[0056] This embodiment also provides a method for installing a grounding stake, using the aforementioned grounding stake, including the following steps:

[0057] S1. Place the outer frame 1 on the ground, activate the first drive assembly 31, and adjust the hammer rod 42 to a suitable hammering height via the slide 33. Specifically, the construction personnel place the outer frame 1 on the ground where the grounding pile needs to be installed. The outer frame 1 is a cuboid frame structure, and the four corners of the bottom of the outer frame 1 are threaded with ground cone feet 11. The construction personnel adjust the levelness of the outer frame 1 by screwing on the four ground cone feet 11, so that the outer frame 1 is placed flat on the ground. Then the construction personnel press down on the outer frame 1 to insert the ground cone feet 11 into the ground, thereby increasing the stability of the outer frame 1. When the ground where the work is carried out is a flat and hard ground, the construction personnel can also unscrew the ground cone feet 11 and place the outer frame 1 directly on the ground. In order to improve the on-site construction speed, the pile body 2 has been pre-inserted into the limiting hole in the opposite direction of the first direction. After that, the construction personnel activate the first drive assembly 31 and adjust the height of the slide 33 on the fixed plate 32 according to the depth that the pile body 2 needs to be drilled into the ground.

[0058] S2. Activate the second drive assembly 41 to move the hammer rod 42 to the lifting position along the first direction. The second drive assembly 41 disengages from the hammer rod 42, and the hammer rod 42 moves to the hammering position in the opposite direction to the first direction under the action of gravity and the elastic force of the spring 43, thereby hammering the pile 2. Specifically, the construction personnel activate the second drive assembly 41, which drives the hammer rod 42 to the lifting position. Then, the second drive assembly 41 disengages from the hammer rod 42. At this time, the hammer rod 42 moves to the hammering position in the opposite direction to the first direction under its own weight and the elastic force of the spring 43, thereby hammering the pile 2.

[0059] S3. Repeat step S2 until the pile 2 is inserted into the ground to a suitable depth. Specifically, after the hammer rod 42 moves to the hammering position to hammer the pile 2, the second drive component 41 can automatically connect with the hammer rod 42 and drive the hammer rod 42 to move along the first direction to the lifting position again. This cycle repeats, and the second drive component 41 can realize multiple automatic hammering of the pile 2, thereby driving the pile 2 into the ground to the specified depth. After the pile 2 is installed, the construction personnel remove the first clamp 51 from the second clamp 52, and then the outer frame 1 can be quickly separated from the pile 2.

[0060] Example 2

[0061] This embodiment provides a grounding stake, which is basically the same as the grounding stake and its installation method in Embodiment 1. The main difference is that in this embodiment, the first driving component 31 is a cylinder, specifically including a cylinder body and a piston rod. An air pump is connected to the outside of the cylinder body. The air pump is used to deliver compressed air into the cylinder body or to draw air from the cylinder body, thereby driving the piston rod to move axially along the cylinder body. The slide 33 is set on the piston rod. The cylinder has a simple structure and is easy to use. At the same time, it has few parts and is not easily damaged, which can effectively extend the service life of the grounding stake.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
